LCInterlocking - FreeCAD Laser Cut Interlocking Module

Goal

This experimental FreeCAD module is used to create interlocking cut parts from 3D to 2D SVG. It was created for laser cutting but can work with CNC router.

Important Note:
This is still experimental and as a consequence, not reliable. You must check parts before doing the laser cut.
Please double check the results of this module!
